PROBLEM TO BE SOLVED: To provide a structure of a CCFL capable of driving in parallel. SOLUTION: A lamp driving device includes a plurality of cold-cathode-ray tube lamps (CCFL) connected in parallel, a first current limiting part connected to the plurality of cold-cathode-ray tube lamps and adjusting capacity of supplied power capable of discharging the cold-cathode-ray tube lamp, and an inverter changing capacity of transmitted AC power and supplying the changed AC power to the first current limiting part. Like this, a fraction defective can be minimized as well as a manufacturing cost of CCFL can be reduced by the CCFL structure capable of driving in parallel. COPYRIGHT: (C)2006,JPO&NCIPI |
